[0033] like Figure 1-5As shown, the utility model provides an automatic magnetizing device for NdFeB bonded magnetic rings, comprising a frame 1, a feeding mechanism 2, a storage mechanism 3, a divider disc 4, a magnetizing mechanism 5 and a control box 6, wherein the feeding mechanism 2 comprises a circular vibration disc 21, a straight vibration device 22 and a feeding track 23, wherein the circular vibration disc 21 comprises a first discharge port 211, wherein the feeding track 23 comprises a second loading port 231 and a second discharge port 232, wherein the first discharge port 211 is connected to one end of the straight vibration device 22, wherein the other end of the straight vibration device 22 is connected to the second loading port 231, wherein the second discharge port 232 is provided with a first opening, wherein the storage mechanism 3 comprises a product placement component 31 and a clamping and blocking component 32, wherein the product placement component 31 comprises a hollow cylinder 311 and a supporting component 312. The central axis of the hollow cylinder 311 coincides with the central axis of the first opening, the clamping and blocking assembly 32 comprises a clamping jaw 321 and a clamping jaw cylinder 322, the clamping jaw 321 comprises an inwardly concave arc portion and a blocking block at the bottom, the hollow cylinder 311 is arranged in the arc portion and is placed above the blocking block, the clamping jaw 321 is connected to the clamping jaw cylinder 322, the material storage mechanism 3 is arranged at the top of the divider disc 4, the divider disc 4 is arranged at the top of the frame 1, a groove is provided at the top of the frame 1, the magnetizing mechanism 5 is arranged in the groove, the feeding mechanism 2, the material storage mechanism 3, the divider disc 4 and the magnetizing mechanism 5 are all electrically connected to the control box 6, and the divider disc 4 can rotate clockwise along the central axis.

[0034] Furthermore, there are four material storage mechanisms 3 , which are evenly spaced and arranged on the divider disc 4 .

[0035] Furthermore, the control box 6 includes a start switch and a pause switch for controlling the start and pause of the device, and can also be used to set an upper limit of the number of products in the product placement component 31.

[0036] The control box 6 is electrically connected to the feeding mechanism 2, the storage mechanism 3, the divider disc 4 and the magnetizing mechanism 5, and the feeding mechanism 2, the storage mechanism 3, the divider disc 4 and the magnetizing mechanism 5 are controlled to cooperate with each other to complete the transportation and magnetization of the NdFeB bonded magnetic ring. The NdFeB bonded magnetic ring is transported to the storage mechanism 3 through the feeding mechanism 2, rotated to the second storage mechanism 302 through the divider disc 4, and magnetized using the magnetizing mechanism 5 to realize the automation of transportation and magnetization. Among them, 100-200 pieces of NdFeB bonded magnetic rings (here pcs represents the plural number of the number, the number of pieces, and the number of units) can be placed in the product placement component 31 according to the different sizes of the NdFeB bonded magnetic rings, so that multiple NdFeB bonded magnetic rings can be magnetized at the same time. The utility model can replace manual work and save a lot of cost and time.

[0037] In a feasible embodiment, it also includes a unloading mechanism 7, which includes a unloading track 71 and a product collecting device 72. The bottom of the unloading track 71 is in contact with the top outer edge of the frame 1, and it is arranged at the center of the top outer edge of the frame 1. The end of the unloading track 71 close to the divider disc 4 is higher than the end away from the divider disc 4. The end of the unloading track 71 away from the divider disc 4 extends into the product collecting device 72. The product collecting device 72 is arranged at the top of the side of the frame 1.

[0038] Since the end of the unloading track 71 close to the divider disc 4 is higher than the end away from the divider disc 4 and is inclined, when the NdFeB bonded magnetic ring falls onto the unloading track 71, it will slide into the product collecting device 72. The operator can collect and conduct quality inspection on the NdFeB bonded magnetic ring in the product collecting device 72.

[0039] In a feasible implementation scheme, the magnetizing mechanism 5 includes a magnetizing head 51 and a lifting cylinder 52. During magnetization, the lifting cylinder 52 drives the magnetizing head 51 to rise. After magnetization is completed, the lifting cylinder 52 and the magnetizing head 51 descend.

[0040] The magnetizing head 51 is used in conjunction with the rising cylinder 52. The magnetizing head 51 is used to contact the NdFeB bonded magnetic ring. During the magnetization process, it generates a magnetic field and transfers it to the NdFeB bonded magnetic ring that needs to be magnetized to magnetize it. The rising cylinder 52 is a pneumatic actuator that can provide pressure and motion control, and is used to control the movement of the magnetizing head 51 to jointly complete the magnetization operation of the NdFeB bonded magnetic ring. Through their synergistic effect, an efficient and accurate magnetization process can be achieved. Among them, the connection and cooperation between the magnetizing head 51 and the rising cylinder 52 belong to the prior art and are not discussed in detail in this application.

[0041] In a feasible embodiment, it also includes an electric control box 8, which is electrically connected to the control box 6. The electric control box 8 is arranged in the rack 1. The electric control box 8 includes a power start switch. The electric control box 8 is installed with a control power supply and auxiliary electronic components for managing and controlling the power supply and the operation of electronic equipment, providing power protection, and ensuring the stability of the equipment.

[0042] See also Figure 4In this embodiment, the storage mechanism 3 includes a product placement component 31, a clamping and blocking component 32 and a base 33. The product placement component 31 includes a hollow cylinder 311 and a support component 312. The central axis of the hollow cylinder 311 coincides with the central axis of the first opening. The clamping and blocking component 32 includes a clamping jaw 321 and a clamping jaw cylinder 322. The clamping jaw 321 includes an inwardly concave arc portion and a blocking block at the bottom. The hollow cylinder 311 is arranged in the arc portion and placed above the blocking block. The clamping jaw 321 is connected to the clamping jaw cylinder 322. A second opening is arranged in the base 33. The central axis of the second opening coincides with the central axis of the hollow cylinder 311. The width of the second opening is equal to the width of the hollow cylinder 311.

[0043] Furthermore, the divider disc 4 comprises four grooves, which are arranged below the material storage mechanism, and the widths of the four grooves are equal to and correspond one to one to the second openings on the four material storage mechanisms.

[0044] The NdFeB bonded magnetic ring falls into the first storage mechanism 301 through the second discharge port 232. Since the clamping blocking assembly 32 includes a blocking block at the bottom and the clamping blocking assembly 32 is in a closed state at this time, the blocking block can prevent the NdFeB bonded magnetic ring from falling and place it in the hollow cylinder 311. The divider disc 4 rotates 90 degrees in a clockwise direction to the position of the second storage mechanism 302. The rising cylinder 52 drives the magnetizing head 51 to rise. The magnetizing head 51 extends into the groove of the divider disc 4 and contacts with the NdFeB bonded magnetic ring in the product placement assembly 31 to perform a magnetizing operation. After the magnetization is completed, the magnetizing head 51 descends, and the divider disc 4 rotates 90 degrees in a clockwise direction to the position of the third storage mechanism 303. The clamping claw cylinder 322 controls the clamping claw 321 to open, and the NdFeB magnetic ring falls onto the unloading track 71 and slides into the product collecting device 72 to complete the unloading operation.

[0045] See also Figure 5 In this embodiment, the feeding mechanism 2 includes a circular vibration plate 21, a straight vibration device 22 and a feeding track 23. The circular vibration plate 21 includes a first discharge port 211, and the feeding track 23 includes a second loading port 231 and a second discharge port 232. The first discharge port 211 is connected to one end of the straight vibration device 22, and the other end of the straight vibration device 22 is connected to the second loading port 231. The second discharge port 232 is a first opening.

[0046] Furthermore, the width of the feeding track 23 can be customized according to the diameter of the NdFeB bonded magnetic ring.

[0047] During use, the user places the NdFeB bonded magnetic ring in the circular vibration disk 21, and the NdFeB bonded magnetic ring makes a circular motion in the circular vibration disk 21, so that the NdFeB bonded magnetic ring is arranged in an orderly manner and enters the straight vibrator 22 from the first discharge port 211. The straight vibrator 22 vibrates to ensure smooth transportation of the NdFeB bonded magnetic ring, enters the feeding track 23, and is transported from the second loading port 231 to the second discharge port 232, and then falls from the second discharge port 232.

[0048] The circular vibration plate 21 can help remove impurities in the NdFeB bonded magnetic rings through efficient and rapid vibration movement, and arrange them in an orderly manner for transportation, thereby improving the transportation efficiency and magnetization efficiency of the NdFeB bonded magnetic rings.

[0049] Working principle:

[0050] When in use, the operator turns on the power start switch of the electric control box 8 and the start switch of the control box 6, and the equipment starts to run. The operator puts the NdFeB bonded magnetic ring in the circular vibration disk 21, and the circular vibration disk 21 vibrates to send the NdFeB bonded magnetic ring into the direct vibrator 22. The direct vibrator 22 transports the NdFeB bonded magnetic ring to the feeding track 23 by vibration, and falls from the second discharge port 232 of the feeding track 23 and enters the hollow cylinder 311 of the product placement component 31. The clamp 321 is in a closed state, and the blocking block in the clamp 321 prevents the NdFeB bonded magnetic ring from falling, so that the NdFeB bonded magnetic ring is arranged in sequence from bottom to top. When the placement upper limit is reached, the feeding mechanism 2 stops running, the divider disk 4 rotates 90 degrees clockwise along the central axis, and the feeding mechanism 2 resumes running, and the storage mechanism at the position of the first storage mechanism 301 continues to transport the NdFeB bonded magnetic ring. Input, at this time, the storage mechanism at the position of the second storage mechanism 302 starts the magnetization operation, the rising cylinder 52 drives the magnetization head 51 to rise, the magnetization head 51 extends into the groove of the divider disc 4 and the second opening of the base 33 to contact the lowermost NdFeB adhesive magnetic ring, and the magnetization operation is started. After the magnetization is completed, the rising cylinder 52 and the magnetization head 51 descend, the divider disc 4 rotates 90 degrees clockwise along the center axis, the clamping jaws 321 open, the NdFeB adhesive magnetic ring falls into the unloading track 71, and slides from the unloading track 71 to the product collecting device 72. The divider disc 4 rotates 90 degrees along the center axis, and the above steps are repeated until all the unmagnetized NdFeB adhesive magnetic rings are magnetized. The operator turns off the start switch of the control box 6 and the power start switch of the electric control box 8. The operator can collect the NdFeB adhesive magnetic rings in the product collecting device 72 and conduct quality inspection.
